Is the manifesto also considered propaganda media? What about analysis of that manifesto, or discussions about how to prevent attacks like this based on the contents of the manifesto, especially if they contain excerpts?

Should we ban news agencies from even reporting on attacks like this? Keep in mind that news-coverage especially has been shown to incite copy-cat attacks.
